    • Design considerations for application of SiPMs in nuclear imaging 

      Efthimiou, N.; Argyropoulos, G.; Georgiou, M.; Fysikopoulos, E.; David, S.; Loudos, G.; Panayiotakis, G. (2010)
      Silicon Photomultiplier (SiPM) detectors are attractive candidates for the replacement of Photomultipliers in nuclear imaging. They are compact, provide high gain with low Vbias and have fast response. In addition, SiPMs ...
    • Initial results on SiPM array based on a symmetric resistive voltage division readout 

      David, S.; Georgiou, M.; Fysikopoulos, E.; Efthimiou, N.; Paipais, T.; Kefalidis, L.; Loudos, G. (2012)
      The aim of this study is to design and apply a symmetric resistive voltage division matrix to read out the compact silicon photomultiplier array (SPMArray2 by SensL) photodetector for possible applications as gamma or PET ...
    • A simple statistical model for turbulence-induced fading in free-space optical systems 

      Chatzidiamantis, N. D.; Sandalidis, H. G.; Karagiannidis, G. K.; Matthaiou, M. (2010)
      In this paper, we propose the Inverse Gaussian (IG) distribution, as a less complex alternative to Log-normal (LN), to describe turbulence-induced fading in free-space optical (FSO) systems operating in weak turbulence ...
    • Simulating the reliability of radio links during superior solar conjunctions 

      Stocker A.J., Argyriou A., Giorgetti A., Paolini E., Siddle D.R., Tortora P., Zeqaj A., De Vicente J., Abello R., Mercolino M. (2018)
      Some results so far achieved in the framework of the HELIOS (Highly rEliable LInks during sOlar conjunctionS) Project, founded by the European Space Agency (ESA), are presented. The purpose of the project is the definition ...
    • A Tractable Model for Turbulence- and Misalignment-Induced Fading in Optical Wireless Systems 

      Sandalidis H.G., Chatzidiamantis N.D., Karagiannidis G.K. (2016)
      Composite models for the combined effect of both scintillation- and misalignment-induced fading in terrestrial optical wireless systems are often expressed in terms of higher order special functions, making, thus, the ...
    • Α dual-hop equivalent structure of a generalised multi-hop free-space optics network 

      Androutsos N.A., Nistazakis H.E., Sandalidis H.G., Leitgeb E., Tombras G.S. (2021)
      The performance of free-space optics links strongly depends on scintillation effects caused by the atmospheric turbulence appearance. A widely adopted way to counterbalance the expected deterioration due to scintillation ...
